I've had this book for quite a while, having received it in an OwlCrate sometime in the last year or two, but it sat in my "to-read" pile the whole time. Up until a month ago, when I finally added it to the equally large stack of books that I'm "actively" reading.
It was worth the wait.
The book is beautifully written capturing the main characters' incredibly different personalities in a way that keeps you rooting for both of them, even when they're at odds. No side character falls flat or leaves you feeling short changed, and the twists and turns left me utterly shocked. There were multiple parts of the book that I never saw coming, which is always an impressive feat in any fictional work.
If I'm honest, I have one major gripe with the book - the cliffhanger ending. I hate cliffhangers with a passion. If the writing is good, I'll read the sequel. If things are left unfinished, I'll read the sequel. But give me a cliffhanger and no matter how much I adore the story or the author or the characters I'll scrap the book and refuse to read it's brothers out of pure spite. At this point, the sequel is available for my purchase, but just the knowledge that I would've been left hanging for a year while the author laughed at my broken heart is simply, unforgivable.
That being said, if cliffhangers don't bother you, or if you're savvy enough to get both Grace & Fury and the sequel Queen of Ruin at the same time, I would recommend Tracy Banghart's brain child wholeheartedly!
